I sold the truck, otherwise I'd take another picture, but it shows the new carpet up against the stock carpeted back wall panel.
I do actually have a couple of other pieces of advice. If you do end up replacing your carpet, when pull up the door sills, don't. The clips that hold them in place go through the floor, tap them up from under the truck so that your not pulling the metal clip out by the thin plastic of the sill. Then when you are putting the sill back get yourself some thin safety wire or something similar and loop it through each of the sill clips. Then pull each one of those wires through the hole in the floor, and pull the wires downward as you tap the sill from above. This way you are guaranteed to have the clips lined and your much less likely to crack the sill.
The sills themselves are pretty thick, but on the back side where the clips attach it's super thin. Also if you decide to replace the clips, take Dremel to them and cut them off, your just going to mess up the sill trying to pull them off. The clips are about $3-4 each, and the only place I could find them was eBay. GM DOOR SILL SCUFF PLATE RETAINER KIT (QTY 10) 15711541 | eBay
